Title: Automatic opening and closing device for stool seat and stool lid
Inventor: OTSUKA YOSHIHIRO
IPC: A47K13/10
Filed: 1994-03-09
Abstract: PURPOSE:To provide an automatic opening and closing device which is structured simply and ecomonically, and excellent in durability, by placing a decelerating mechanism and a clutch mechanism between a driving motor and a driving shaft, where the decelerating mechanism comprises a wormgear, a friction gear, a feed screw rod, and a slider, etc. CONSTITUTION:The rotation driving force of a driving motor 2 in a decelerating mechanism A is transmitted to the friction gears 12 and 16 through a wormgear 8 to rotate feed screw rods, 13a and 13b, of a clutch mechanism B. Accordingly, a slider 17 slides up and down in the axial direction and an arm member 22 turns to rotate a driving shaft 19. Consequently, a stool seat 20 and a stool lid 21 open and close automatically against a stool main body. On the other hand, when opening and closing manually, for instance, the stool lid 20, because the slider 17 moves the feed screw rod 13 against an elastic means 15 of a holding means 14, the engagement between the friction gears 12 and 16 is released and the driving force from the driving shaft 19 will not be transmitted to the decelerating mechanism A. This mechanism produces an automatic opening and closing device which is simplified and unexpensive, and excellent in durability as well.

Title: Method and apparatus for measurement of wind velocity
Inventor: NONOMURA YOSHITAMI
IPC: G01F1/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To measure a wind velocity at low costs by using an apparatus which is easy to handle. SOLUTION: Water is supplied to every sensor 4 from a tank 22 through a pipe 6. Cloth is mounted on, and attached to, the tip of every sensor 4, and the water is absorbed by the cloth. When an air current is generated, the water which is absorbed by the cloth is evaporated, and, as a result, a water level inside the tank 22 is lowered. Water is supplied properly to the tank through a water supply pipe 28 by the action of a float 36 and that of a valve 34, and the water level is kept constant. Then, a flowmeter 10 measures the flow rate of the water flowing in the water supply pipe 28 so as to output its signal to a personal computer 12. The personal computer integrates the flow rate so as to find an evaporation amount, and a wind velocity is found on the basis of the evaporation amount by using a conversion table.

Cooling of work roll by approaching the start point of cooling can be executed over approximately the whole rolling time. Heat dissipation efficiency is high and this method is remarkably effective on the reduction of skin roughening and thermal crown of roll.

IPC: G11B11/08
Filed: 1983-03-11
Abstract: PURPOSE:To enable extremely easy and inexpensive manufacture of a large-sized disc and to permit long-time recording and reproducing by forming an insulating film having an electric charge accumulating function on a polycrystalline or amorphous semiconductor substrate having <=20mum thickness. CONSTITUTION:A semiconductor disc is formed by forming an extremely thin amorphous silicon layer 2 having <=20mum, for example 1mum thickness on a metallic substrate 1, and forming successively an SiO2 layer 3 having about 20Angstrom  thickness and Si3N4 having about 300Angstrom  thickness thereon. A voltage signal 6 corresponding to the information signal to be recorded is impressed between a conductive recording stylus 5 and the substrate 1 and the electric charge in the amorphous silicon substrate corresponding to the impressed signal voltage is transferred through the film 3 by a tunnel effect to the Si3N4 film 4 and is recorded in the form of successive trapping of the electric charge. The capacity Co of the Sn3N4 film is always constant but capacity Cv of the depletion layer changes and the thickness tm of the amorphous depletion layer changes with the accumulating condition of the charge in the Si3N4 film, i.e., the recording condition and therefore the reading out of information is accomplished by detecting the change in the capacity Cv of the depletion layer.
